Gameboid Sound Delay

Okay, so I so downloaded the full Gameboid Emulator onto my phone last week, and up to now, everything has been running fine.

There's a delay between the time you see an action performed on screen and hear the correlating sound. For example, I hear Link's voice a half-second after he swings his sword.

I know the ROMs are all okay because they run perfectly on VisualBoyAdvance on my PC. There were no major changes to my phone when this happened besides leaving my house's Wi-Fi Hotspot, which I highly doubt was the trigger because it worked fine in other places this week.

This applies to all the Gameboid ROMs GBCoid runs perfectly. Any thoughs? I have the original DroidX.
